In primitive age, man survived by hunting wild animals and by using forest produce. During this period, man was a wanderer and he roamed in the forests in search of food which was always uncertain. His daily needs were nothing but food. In that age, he was nothing but a wild creature. The sheltering places for him were only in the trees or in the caves. In cold regions, he managed his life by hunting wild animals. In temperate regions, besides hunting, he survived by eating roots and other vegetation. He lived mostly near water sources so that he might get water to quench his thirst.
